摘要

@@ A laser diode (LD) cladding-pumped cw Tma+-doped silica fibre amplifier is reported that provides up to 3 W output with the slope efficiency nearly 30%. The gain fibre is 27.5/400μm D-shaped Tm3+-doped silica doublecladding fibre, and the input signal sources is an LD-pumped Tm3+ : YAP lasing at 1.99μm. The measured amplified spectrum only stretches a little relative to the input signal spectrum. This is the first report to the authors' knowledge of general experimental investigation of cladding-pumped Tm3+-doped fibre amplifier of high power cw at 1.99μm.
